L8602 Overview
The UTC L8602 is a programmable low power depletion mode FET bias and mixer controller intended primarily for satellite Low Noise Blocks (LNBs). Designed to provide system flexibility the UTC L8602 can be programmed to bias six low noise amplifier (LNA) stages or four LNA and two active mixer stages, allowing the UTC L8602 to be used in several system designs. bining an advanced IC process and packaging techniques,...
